MACHINE FOR REMOVING WATER-HAIRS FROM PELTS, 800.

SPECIFICATION forming part of Letters Patent No. 408,879, dated August13, 1889. Application filed March 13, 1889- Serial No. 303,121- (Nomodel.)

To all whom ii may concern.-

Be it known that I, ANTON HEDBAVNY, of the city, county, and State ofNew York, a citizen of the United States, have invented certain new anduseful Improvements in Machines for Removing YVater-Hairs from Pelts, ofwhich the following is a specification.

This invention relates to an improved machine for removing the stiffWLi361'htl1S from [D pelts by the action of a metallic conductor that isheated to incandescence by an electric current from a dynamo or othersource of electricity; and the invention consists of a machine'forremoving water-hairs from pelts,

I5 comprising a knife-edged bar, means for intermittently feeding thepelt over said knifeedged bar, a serrated guard-comb at one side of saidbar, a rotary brush at the other side of the same, said brush serving tocomb the Wool in downward direction away from the Water-hair andincandescentmetallic conductor, which is supported on oscillating leversthat are intermittently actuated by suitable cam mechanism, saidmetallic conductor being connected to a suitable source of electricity.

In the accompanying drawings, Figure 1 represents a side elevation,partly in vertical longitudinal section, of my improved machine forremoving water-hairs from pelts; and Fig. 2 is a top view of the samewith some of the parts broken away.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the supporting-fra1ne of myimproved machine for removing water-hairs from pelts. The frame Asupports in suitable guides a vertically-adjustable knife-edged bar B,over which the pelts to be treated are stretched. The pelts arepreferably basted onto a suitable apron of canvas or other suitablefabric and wound on a roller 1), from which the pelt is passed over theedge of the bar B and then in downward direction between two feed-rollsd d, which serve to move the pelt intermittently over the edge of thetransverse bar B.

At one side of the knife-edged bar is arranged a pivoted guard plate orcomb 0, having a serrated edge, which is adjusted higher or loweraccording to the position of the knifeedged bar B, by means of.set-screws e.

The guard-comb C serves to retain the soft hair or wool of the peltbefore the same passes over the edge of the transverse bar B. Theguard-comb 0, however, does not retain the stiff water-hairs, butpermits them to straighten up immediately as they pass the serrated edgeof the blade, so as to project vertically in line with the axis of thetransverse bar B, or nearly so, in upward direction. At the oppositeside of the knife-edged bar B is arranged a rotary brush D, which ispreferably made of longitudinal serrated rubber strips, said brush beingrotated at considerable speed in bearings of the supporting-frame by abelt-and-pulley transmission from the driving-shaft S.

The quick brushing action exerted by the roller D on the pelt at theopposite side of the knife-edged bar combs the wool on that side indownward direction, so that the waterhairs project upward and can beburned oif by a metallic conducting rod or bar F, which is supportedtransversely above the edge of the bar B on arms f, attached tooscillating levers f, which latter are fulcrumed to the rear endsv bysuitable springs f with the frame A.

The metallic conductorFis connected with the poles of a dynamo or othersource of electricity and kept by the current from the same in anincandescent state. The levers f receive an intermittent oscillatingmotion by cams f that engage anti-friction rollers f at the rear ends ofthe levers f, so that said incandescent conductor is intermittentlylowered and applied to the stiff projecting waterhairs of the pelt so asto burn the same, without, however, injuring the fine hairs or wool,which are retained at one side of the bar B the rotary roller D. The camf at one side of the driving-shaft S is provided with an additionalcrank-disk g, which is connected by a pivot-link g with an arm g that ispivoted to the shaft of a ratchet-wheel h, which is engagedby aspring-actuated pawl h, pivoted to the arm g so as to be turned foradistance of one or more teeth at each rotation of the crankdisk g onthedriving-shaft S. To the shaft of the ratchet-wheel is further keyedabevelwheel 2', which meshes with a pinion t" on a by the guard-comb Cand at the other side by v supporting-frai'ne A and connected at theirshort longitudinal shaft "F, that turns in bearings of the frame A andis provided with a worm 1", that engages with a worm-wheel i" at the endof the shaft of the feed-roller (7, so as to move intermittently at eachrotation of the driving-shaft S. The feed-rolls (Z (1' press tightly onthe apron and pelts attached, so as to feed the same intermittentlyforward over the knife-edged bar. During the time when the pelt is atrest the incandescent conductor is lowered, so as to burn off theprojecting waterhairs. As soon as the burning oil": of the water-hairsis accomplished on the narrow strip of pelt above the edge of the bar,the incandescent conductor is removed away from the pelt and the peltfed forward by its intermittentlyoperated feed mechanism, so as to bringthe adjoining strip of pelt over the edge of the bar B the hairs ofwhich are burned oi't' by the incandescent conductor, and so on.

At each rotation of the d rivin shaft a narrow strip of pelt is thus fedover the knifeedged bar and a new set of water-hairs burned oit by theaction of the incandescent conductor 1 so that iinally,when the entirepelt has been moved over the knife-edged bar, all the projectingwater-hairs of the same are burned off without injury to the line hairsor wool of the same. The pelt is then removed from the machine, rubbedwith hot sand, and then carefully washed with water, so that the burnedhair and the smell of the same are removed, after which the pelts areready for dyeing and for use.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. The combination of a transverse knifeedged bar,means for intermittently feeding the pelt over said knife-edged bar, aguardcomb at one side of said knife-edged bar, a rotarybrush at theopposite side of the same, and an intermittently-oscillatingincandescent conductor located above the knife-edged bar, so as to burnoff the projecting waterhairs when itisbrought in contact therewith,substantially set forth.

2. The combination of a transverse knife edged bar,intermit-tently-actuated feed-rolls for moving the pelt over the edge ofsaid bar, an adjustable guard-comb having a serrated edge at one side ofsaid bar, a rotarybrush at the other side of the same, an incandescentconductor, fulcrumed levers supporting said conductor, and. mechanismfor oseillatin said levers and conductor, so as to cause it to approachto or recede from the edge of the pelt above the bar, substantiallyasset forth.

In testimony that I claim the foregoing as my invention I have signedmyname in presence of two subscribing nitnesses.
